RAILWAY-CAR BRAE.

Specification of Letters Patent.

Patented Oct. 27, 1908.

Application filed August 5, 1908. Serial No. 447,021.

To all whom it may concern:

Be it known that I, SETH A. CRoNE, a citizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Railway- Car Brakes, of which the following is a specification.

The invention relates to improvements in railway car brakes, and it consists in the novel brake-head hereinafter described and particularly pointed out in the claims.

My invention. pertains moreparticularly to a brake-head having novel means for securing to it the end'of a brake beam, the object being to provide durable and efficient means for securing the head in rigid position after it has been applied on the beam and given its desired angular adjustment.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which:

Figure 1 is a side elevation of a brakeshoehead constructed in accordance with and embodying the invention; Fig. 2 is an elevation of the same taken from the back of the head; Fig. 3 :is a transverse section of the same on the dotted line 33 of Fig. 1;

Fig. 4: is a face view of the head; Fig. 5 is a detached top view of a hinged locking bar employed in securing the head on the end of a beam; Fig. 6 is a side View of the same; Fig. 7 is a detached top view of ablock which cooperates with the bar shown in Fig. 5 in securing the head in position; Fig. 8 is a side elevation of the same; Fig. 9 is an enlarged detached elevation of a customary construction of sleeve fitted on the end of a brake-beam to receive the brake-head; and Fig. 10 is an end view of the same.

In the drawings, designates the head as a whole, and this head except with respect to the locking features hereinafter described, is of standard construction and therefore does not require detailed description.

Below the usual sleeve 16 the head 15 is equipped with the features of my invention, and the head is modified to adapt it for the same. I provide the head, below the sleeve 16, with the downwardly extending portion 17 affording a chamber 18 3) whose outer portion is adapted to receive the head of the bolt 19 and whose inner portion is of greater width and adapted to receive the locking block 20, the head of the bolt and the sides of the block snugly fitting the side walls of the chamber 18. The chamber 18 at its inner portion is open at its bottom so that the block 20 at its lower portion may slide downwardly through the same, and said chamber at its inner portion is formed with a base 21 containing a hole 22 for the bolt 19, said base 21 preventing the bolt from sliding downwardly and escaping from the head. At the front of the chamber 18 is a vertical transverse flange 23 which serves to confine the block 20, said flange 23 being cast integrally with the head and ex tending between the sides thereof, as shown in Fig. 8. The chamber 18 is formed at the outer corners of its wider or block receiving portion with shoulders 24.- upon which shoulders 25 of the block 20 may rest when said block has descended to its lower position. The shoulders 25 are formed by recessing the opposite back corners of the block 20, as denoted at 26 (Figs. 7 and 8), and one object of the shoulders 25 and shoulders 24. is to prevent under all circumstances the descent of the block 20 entirely through the bottom of the chamber 18. The block 20 applied to position by being inserted into the chamber 18 from the upper end thereof, and the bolt 19 is applied to position by be ing inserted downwardly into its portion of the chamber 18 with the stem of the bolt passing through the hole 22.

Suitably below the flange 23 and formed on the opposite sides 27 of the head are the curved flanges 28 which form sockets for vthe trunnions 29 of the locking bar'SO,

whereby said bar becomes pivotally secured or hinged to the head. There is an open space between the flanges 28 and flange 23, and hence the end of the bar 30 may be inserted between said flanges and have its trunnions 29 seated within the sockets of the flanges 28. The locking bar 30, when in position, extends from the flanges 28 rearwardly below the block 20 and chamber portion 17 of the head, as shown in Fig. l, and the outer end of the bar 30 is formed with a hole 31 through which the bolt 19 passes. The bar 30 is of substantial character, as indicated in Figs. 5 and 6, and at its outer end has flat upper and lower surfaces, the upper surface matching the lower surface of the part 17 of the head and the lower surface of the outer end of the bar being made flat to receive a nut 32 and preferably a nut lock 33. The nut lock 33 is shown as being formed from a strip of metal having one end bent downwardly against the side of the nut 32 and the other end bent upwardly against the side of the front end of the bar 30, as shown in Fig. 2. The bar 30 has an upwardly curved intermediate portion 4a which is adapted to receive and form a seat for the lower end of the locking block 20, as indicated in Fig. 1.

My invention resides in the provision of the locking bar 30 with the block 20 and cooperating features, said bar 30 being hinged and affording a seat for the block 20 and also means for enabling the vertical adjustment of said block. By lowering the nut 32 on the bolt 19 the outer end of the bar 30 may be lowered and thus effect the lowering of the block 20. By tightening the nut 32 upwardly on the bolt 19 the bar 30 will be forced with great power against the block 20 and cause the latter to bind against the end of the brake-beam or against the end of the sleeve thereon should such beam possess a sleeve.

Ordinarily the brake beams employing the heads of the character shown, will be provided with the sleeve 34 of usual construction, said sleeve fitting upon the compression and tension or truss members at the ends of the brake beams and being adapted to receive the sleeve 16 of the brake-head. The sleeve 34 is formed with annular surfaces 35 which snugly fit against the inner surfaces of the sleeve 16 and with an annular recess 36 located between said annular surfaces 35 and preferably grooved or serrated, as at 37, to be engaged by the serrations or grooves formed on the upper end of the block 20, the serrations on the sleeve and block cooperating to enable the rigid securing of the head on the sleeve.

When it is desired to apply the head on the sleeve 34 the bar 30 should be lowered until the block 20 is just below the ring 16 and the head, and thereupon the head may be pushed directly onto the sleeve. After the head has been properly adjusted angularly, .it will be rigidly secured in position by tightening the nut 32 against the outer end of the bar 30, the latter being thereby caused to turn upwardly on its trunnions 29 and force the block 20 into rigid engagement with the serrations on the sleeve 34. When it may be desired to readjust the head the nut 32 may be lowered so as to effect the release of the block 20 from the sleeve 34, and thereupon the head may be angularly adjusted and again secured by tightening the nut 32 against the bar 30. Should it be desired to remove the head entirely, the nut 32 would be screwed downwardly on the bolt 19 until the bar 30 has lowered sulficiently to enable the block 20 to pass entirely below the ring 16.

In the event that during the use of the brake the nut 32 should become lost, the 7 bolt 19 could not leave the brake-head, but

the bar 30 would turn downwardly on its trunnions 29 and the block 20 would settle down partly through the bottom of its chamber. 18. Under the conditions stated the bar 30 would not become detached from the head nor would the block 20 descend entirely through the chamber 18 and become lost, since upon the descent of the block 20 its shoulders 25 would engage the shoulders 24.- on the head and become arrested thereby. The shoulders 24 are intended to permit the block 20 to descend, in case of accident, sufficiently far to enable it to engage the upper surface of the bar 30 so that said block may aid in preventing the bar from being carried out of the flanges 28.

The hinged bar 30 and screw 19 enables a very rigid binding of the block 20 against the sleeve 3i and consequently assures the firm securing of the brakehead on said sleeve. The brake-head is prevented from moving axially or endwise off the sleeve 34 by the gripping action of the block 20 and also by reason of the fact that the operating end of the block 20 is, when in service, confined within the recess 36 of said sleeve. I do not confine the invention to the use of the sleeve 34L, since when the ends of the beam are cylindrical to receive the sleeve or ring 16 of the head, said sleeve is not required. It has long been customary, however, to equip the ends of brake-beams with sleeves 34: and I prefer the employment of said sleeves.

\Vhat I claim as my invention and desire to secure by Letters Patent, is:

1. A brake-head, and means carried thereby for securing the same comprising a hinged bar, means for moving and securing the free end of said bar, and a locking-block above and engaged by said bar; substantially as set forth.
